In a​ race, 29 out of the
50
swimmers finished in less than
50 minutes. What percent of
swimmers finished the race in less than
50 ​minutes? Write an equivalent fraction to find the percent.

58% - 29/50(equivalent fraction)

Step-by-step explanation:

29/50 x 2 = 58/100 convert to decimal, 0.58, convert to percent, take decimal symbol and put it to digits to the right, 58%

the reason I doubled the fraction was to make it 100 so you can convert into a decimal a lot easier.

how I got 29/50, 29 out of 50 is the same thing is 29/50.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
